Zen Cooler Review

zencoolerWhat is Zen Cooler? Common fans do not change the air temperature, but they make you feel cooler helping to evaporate the sweat from your body. But for you to really cool down, you need a device that will lower the air temperature, like the Zen Cooler. Designed for personal use, this little appliance is an evaporation-based cooler that uses a water tank to cool the air it blows at you.

Features of Zen Cooler

Voltage: Bivolt
Speeds: 3 speeds
Capacity of the tank: 350ml
Autonomy: up to 8 hours
Dimensions: 17cm cubic

Zen Cooler – Design

Most evaporative coolers are fairly large devices that look more like portable air conditioning units. The ZenCooler is a small cube-shaped cooler, measuring only 17cm x 17cm x 17cm, making it ideal to be placed on a desk. We evaluated a unit in white color, but there are also options in black and blue.

As this is an evaporating cooler, it has a 350ml water tank aside. It’s a bit difficult to remove, but after a few refills, we figured out how to put the tank in and out without any problems.

The water in this tank is absorbed inside the cartridge, spreading evenly over the surface of the cooling system. As the fan in the back blows hot air over the water, it evaporates, cooling the air and adding moisture to it. The water tank provides three to five hours of cooling and the cartridge can absorb about 200 ml of water; refilling when the cartridge is full extends the cooling time from one to three hours, totaling up to 8 hours of cooling.

Controlling the ZenCooler is easy thanks to the buttons on the top panel. With 3 speed settings, there is plenty of room to offer between a gentle breeze to a burst of fresh air.

Tap the 3rd button once and you will turn on the water reservoir light.

Zen Cooler – Performance

Once the cartridge has fully absorbed the water from the tank, ZenCooler can operate at maximum efficiency. The cooling effect depends on many factors, including ambient temperature and relative humidity. Evaporative coolers work best in hot, dry environments.

ZenCooler has a useful guide that shows the expected performance of the cooler: at 25oC with 30% relative humidity, you can expect air output to be 15.4oC; at the same temperature but with 60% relative humidity, the outlet temperature is 19.7 ° C.

Testing in a room with an ambient temperature of 22.8 ° C and 53.2% relative humidity with an external meter, I left the cooler for the first time for 20 minutes to give the cartridge enough time to absorb enough water. When the cartridge was saturated, we measured Zen Cooler output at 16.3 °C.

The AirCooler reported that the entry was 22.3 ° C and the outlet was cooled to 16 ° C. You can see the cooler in action with the thermal imaging camera below: the blue part of the image is cold air.

We measured the maximum air speed at 15cm to 2.1m/sec, dropping to 0.8m/sec at 1m. At minimum speed, the anemometer was not sensitive enough to detect airflow. Compared to a traditional fan, the ZenCooler does not exchange much air, but it does not have to. I found myself surrounded by a draft of cool air that refreshed me much better than a fan.

Being too far away from the device means that you can stop feeling the maximum benefit. Zen Cooler was able to make my desk much more comfortable. Similarly, it is extremely useful for sleeping, keeping your body cool on a hot night.

The noise is not bad at all; It measured 53.9dB at 1m with maximum power. At minimum power, the noise levels were 33.4dB, which is just the room background noise.

The power consumption is excellent. According to the plug-in power meter, the Zen Cooler was consuming 2W at minimum speed and only 6.2W at full power. This is much less energy than an air conditioner would consume. The power consumption is so low that the ZenCooler is powered by a standard micro-USB cable, so it can opperate connected to your computer.

Should You Buy ZenCooler?

Testing the performance on a Summer Day with typical humidity levels for my house, I discovered that ZenCooler was able to produce a much cooler airflow than the room temperature. It made my work environment more comfortable and, thanks to the way it works, so that I could still leave the windows open to breathe fresh air.

Best of all, the running costs are extremely low. Air conditioners will cool an entire room and work better in high humidity environments, but require ventilation and are more expensive to buy and operate. Common fans can cover a larger area, but do not affect the air temperature.

For common use, at a work desk or during sleeping, the ZenCooler is a great way to beat the heat and humidify the air in cases of people suffering from respiratory problems on dry days.

Clean, compact, cheap, with simple controls and easy to use, the ZenCooler is a great way to keep warmth away from you during your day or even during your sleep.
